v This'` invention relates to sun shades and awryings' for windows 'and'doors and it has particular referencetoy fol'dable or collapsibleawnings.

. The principal object of the invention is to Vnrovide an awning of neatand attractive design, con.- structed preferably of sheet metal incollapsible sections, the latter beingv fso related,l when in extendedposition that they will exclude'all direct lrays of the; sun yet willadmit indirect light as well asY air, to dispel. or release heated airtend ing to accumulate under unventilated awnings. Moreover, therelativespacing but overlapping're lationship of the awning'` sectionsprecludes passage of rainwater while Ventilating the: area be heath theawning.

Another object of the invention isto provide a sectional ventilatedawnin-g in which the sections are normally under a tensional forceurging them to extended or open position, to resist which', 'a .pullcord is provided to closelorcollapse theawning sections, having anoperator manipulatable -interiorly of the building on which the awningis installed.v Still another object of the invention is to provide anawning whoseparts are so designed that they lmay .berireadi-ly assembledand disassembled ,for convenient packing and.A shipping and among theparts is a novel form of flashing designed to provide a watertightsealbetween the awning and its mounting surface.

With the foregoing objects in view, the invention. has iurther referenceto certain ieaturesof accomplishment which will become apparent as thedescription proceeds, taken in connection with the accompanying drawingwherein: K

Figure 7- is* a fragmentary perspective view of one of the awningsections.

Sheet metal awnings in collapsible sections are not broadly new, nor itis considered herein to-be new to operate an awning interiorly of thebuilding on which it is installed, but it is considered an improvementin this art to so arrangethe sections of the folding type of awning insu'ch mannerthat entrapment of heated air beneath the awning is avoided,thus contributing much towards the comfort of occupants of the building.` It is considered also a further advancement in' the art relatingto collapsible metal awnings to provide for the entrance of indirectllight while prohibiting passage of rainwater so that the interior of theroom protected by the awning will not be unduly darkened, even on dayswhen the Sun is shining..

Continuing with a more detailed description of the drawing, referencenumeral Ill denotes a stationary hood or mounting section having alongitudinally formed flashing plate l l thereon, the latter in. turn,.being provided with longitudinal channel. lf2 adopted to contain asuitable weatherprooiing compound I3 which seals the upper porition ofthe,` mounting section against passage of moisture between the same andthe wall I4 to Which it is attached by screws I5.

The awning is designed to be dismounted Afor convenient packing andshipping and with this in view, a joint I6 such as shown in Figure 3, isprovided for attaching the awning section Hl to fa substantially'triangular side member l1, the

parts being held together by means of metal screws I8.k This is truealso of the several movable sections which are telescopically relatedand adapted to be foldable under the stationary section i0, hence thesame reference characters are employed to indicate the joints. andretaining screwsthroughout.

The movable sections of the awning include a section I9 and `itstriangular side members 20 and an outer section 2l and its complementaryside members 22. It is to be understood that as many awning. sections asmay be required or de scribed may be incorporated in the awning but inany event, the lower ends of the side members 2D and 22 on each side aremounted on a common pivot 23 situated in the lower end of the sidemember I1 of the stationary mounting section, the said member I1 havinga ange 24 thereon which is secured by means of screws 25 to the Wall I4.

capable of being folded one into the other as they are successivelyraised. This is accomplished by means of a cable 26 adapted to be woundon a spool 21 and which extends upwardly alongside the window frame 28and through an eyelet 29` at the top of the frame, thence through asecond eyelet 30 at the opposite side of the frame, whereupon it extendsoutwardly and is attached at 3| to the lowermost awning section 2i, asshown in Figures 1 and 2. Another length of cable 32 isattached to cable29 at a point below the eyelet 29 at one end and has its opposite endattached at 33 to the opposite end of the lower awning section 2l. Thus,by pulling upon the cable 2S as by winding the same on the spool 1 21,the lower section 2l is raised to aposition within the next section I9,followed by the latter section which disposes both or all of the movablesections underneath the stationary section i0.

Returning to the operating means for the cable 25, the spool 21 on whichit is wound is mounted on a shaft 34 (Fig. l) which extends axially intoa hollow shaft 35, the latter extending through an opening made in thewall 14 and carries a crank 36 on its interior end. A clutch consistingofa boss 31 is mounted on and rotated by the hollow shaft which isadapted to enter a hole (not shown) in one side of the spool 21 torotate the latter in raising the awning sections. A

spring 39 within the hollow shaft 35 normally exerts a force tending toseparate the boss 31 and spool 21 to disengage the clutch. To engage theclutch, the crank 36 is forced inwardly against the resistance of spring39.

The awning sections I9 and 2l are normally urged to open or extendedposition by means of a looped or torsion spring 40 (Fig. 5)., one end ofwhich is affixed by means of a screw 4| to the wall I4 while theopposite end is secured by a screw 42 to an internal flange 43 formedalong one edge of the side member 22 of the lower awning section 2l. Thetension of the spring 40 resists raising of the awning sections, tendingto maintain them in extended position and has the -further eiect toprevent relative movement of the sections by the wind, hence rattlingthereof is minimized or eliminated entirely.

In order that an air pocket beneath the awning ywill be avoided when thesections thereof are extended, there is provided between these sectionsan intervening space 44 better shown in Figure 6. The forward edge ofeach awning sections overlaps the rear edge of the next adjacent sectionbut is out of contiguity therewith to admit indirect light yet excluderainwater. Direct rays .of .the sun on the exposed part of one of the-sections will be reflected by the underside of the overlying portion ofan upper section and through the window protected by the awning, therebydis'- pelling the darkness which would otherwise exist inthe room.

To provide the light admitting and Ventilating openings 44 and yetinsure relative engagement of the awning sections for successive raisingand lowering thereof, the forward edge of each sec- 4 tion is turnedunder as at 45 (Fig. 6) to lie flush against the underside of thesection. This undervturned portion not only reinforces the forward "edgeof the section but from this portion is struck a projection 46 at eachend against which abuts a similar projection 41 which is struck from anunderturned portion 48 on and longitudinally of the next adjacent andlower awning section. The portion 48 also reinforces the rear edge ofeach movable section. Therefore, between the downwardly and upwardlyturned protuberances 46 and 41 respectively, there is an elongated spacel44 through which -air and light may pass but, in view of theoverlapping relationship of the front and rear edges of juxtapositionedsections, there is little likelihood of rainwater entering the opening44 except possibly during a wind of hurricane proportions in which casethe awning will more than--likely be raised or the `window closed.

Manifestly, the construction a shown and described is capable of somemodification and such modification as may be construed to fall withinthe scope and meaning of the appended claim is also considered to bewithin the spirit and intent of the invention.

What is claimed is: v

In a sheet metal awning, the combination comprising a stationarymounting section and a plurality of movable sections successivelydisposed under said stationary section, all but the stationary of saidsections having both its forward and rearward portions turned inwardlyto lie against the undersurface of the section, a protuberance dependingat right angles from each end of the inner edge of the inwardly turnedfor# ward portions of said awning sections, a complementary protuberanceextending upwardly at right angles from each end of the rearward portionof each of said movable sections and adapted to lie in the path of `saidfirst mentioned protuberances to engage ,therewith and to limit thedegree of relative extension of said movable sections, substantiallytriangular side member on each of said awning sections, the side membersof each side of said awning having a common pivotal point and springmeans for imposing ten#- sion on said :awning sections in extendedposition thereof.
